When we're working problems that involve a pendulum, we almost always IGNORE anything else besides gravity.
Anything else besides gravity that could influence the motion of a pendulum is something that we would eliminate if we could.
Those are air resistance, mass of the string, friction at the top suspension point, and the Coriolis force, due to the Earth's rotation, that tries to change the plane of the pendulum's swing.
This question is probably fishing for the answer "<em>friction</em>".
Aristotle and Ptolemy said that earth is in the center and all other planets move in a circular motion around Earth.
Aristotle from Classic Greece and Ptolemy from Roman Egypt agreed on three facts:
- Earth and other celestial bodies are spherical in shape.
- Earth is in the center and all other celestial bodies revolve around it.
- The other planets orbit in a circular path.
This model of the solar system with Earth in the center is called as Geocentric model.
Therefore, Aristotle and Ptolemy said that earth is in the center and all other planets move in a circular motion around Earth.
